SYNOPSIS

DESCRIPTION

These routines return the character, of type chtype, at the current
position in the named window. If any attributes are set for that position,
their values are OR'ed into the value returned. Constants defined in
<curses.h> can be used with the & (logical AND) operator to
extract the character or attributes alone.

Attributes

The following bit-masks may be AND-ed with characters returned by winch.

A_CHARTEXT

Bit-mask to extract character

A_ATTRIBUTES

Bit-mask to extract attributes

A_COLOR

Bit-mask to extract color-pair field information

RETURN VALUE

Functions with a "mv" prefix first perform a cursor movement using
wmove, and return an error if the position is outside the window,
or if the window pointer is null.
